We emphasise the importance of taking into account the species as

We emphasise the importance of taking into account the species assemblage present at any given site and understanding the dynamics of local ambient background conditions, including spatial and temporal variability of turbidity and sedimentation, before setting thresholds in any dredging operation near coral reefs. A combination of reactive (feedback) monitoring of water quality and coral health during dredging activities and spill-budget modelling of dredging plumes to guide decisions

analysis of literature data to test hypotheses to explain differences in sensitivity between coral species greatly benefited from discussions with Onno van Tongeren, Bregje van Weesenbeeck, Tineke Troost, Eric Paling and Monique Grol. The manuscript benefitted from a technical editorial review by John Comrie-Greig, for which we are grateful. The research presented in this work was carried out as part of the Singapore–Delft Water Alliance’s Marine and Coastal Research Program (Theme 2) grant number (R-264-001-001-272). The review formed part of the contributions by PE to the PIANC EnviCom Working Group 108 for the development of best-practice

guidelines for “Dredging and Port Construction around Coral Reefs” (PIANC, 2010). The first author (PE) gratefully acknowledges additional financial support provided through the R&D programs at Delft Hydraulics, Deltares and Sinclair Knight Merz (SKM), without which the completion of this review would not have Meloxicam been possible. ““The focus of the southern Chinese province of Guangdong is the Pearl River (Zhu Jiang) basin and delta, which drains a vast area (some 453,700 km2) of southern China. The river is some 100 km wide at the mouth, with the Special Administrative Regions of Macau and Hong Kong flanking the western and eastern banks, respectively. To put the river in perspective, the Pearl is the second largest river in China, after the Yangtze, with an estimated flow of 9500 m3 second. Guangdong is not just considered the fertile agricultural rice bowl of China it became, in 2005, the most populous province in the country, registering >79 million permanent residents and >31 million migrants who live in it for at least six months of the year. As of 2012, the province’s estimated population of >110 million, was 7.8% of China’s total.
